One of the major concerns in the design of circular prestressed concrete utility poles (hollow or solid) is economy. Several designs can be used in a particular design situation, but the most inexpensive design is of primary interest. Cost optimization of hollow prestressed concrete utility poles was carried out in this study based on design variables, including the inside and outside diameter and the area of prestressing strands at the pole tip. Optimization of poles was also carried out when prestressing is not constant throughout the pole and varies at different sections. The interior penalty function method is primarily used in the cost-optimization process. An optimization program was developed to optimize a given objective function along with its constraints. An initial design package was written to obtain an initial design point in the feasible region of design. A second program known as the flexible tolerance method is also used to optimize the utility poles. Cost optimization of the pole when prestressing is constant or when it varies along the pole is quite possible and can be studied for different design variables. Results of optimization with constant prestress force for two and three design variables provide nearly the same kind of results.
